Today Andreas, HB9HCI and myself we were on HB/OW-001 ( Height: 3238 m / 10623 ft). There were vy poor prop. At home I googled an found this info from Frank, W3LPL!

The most powerful solar flare and CME thus far during solar cycle 25
From W3LPL, Frank Donovan
A solar flare from massive solar region 2786 at 1311Z on Sunday 29 November was the most powerful solar flare and coronal mass ejection (CME) thus far during solar cycle 25. The sun’s activity is now rapidly increasing after a slow increase in activity this year following solar minimum last December
The flare and CME erupted from just behind the southeast solar limb and was not Earth directed. The shock enhancement/glancing blow from the CME may cause unsettled
to active geomagnetic conditions on 1-2 December. There is a
chance for additional M-class solar flares through 2 December and a slight chance for much stronger X-class flares.
The WSA-Enlil model shows the 29 November solar flare and associated coronal mass ejection (CME). Earth is the yellow dot.
